WINDOW-SASH.

SPECIFICATION forming part of Letters Patent N 0. 437,980, dated October'7, 1890.

' Application filed March 17, 1890. Serial No. 344,211. (No model.)

To all whom it may concern:

Be it known that 1, DAVID OROSSER, a citizen of the United States,residing at Cardon a, in the county of Clay and State of Indiana, haveinvented certain new and useful Improvements in IVindow-Sashes; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in the means of fastening glass inwindowsashes, doors, picture-frames, show-cases, and frames of allkinds; .and the objects of my improvements are, first, to dispense withthe use of putty, joints, nails, 850., and in securing the glass in aframe and at the same time to make the glass easily detachable whenrequired by the use of a single locking-strip inserted in such a manneras to render unnecessary the use of brads or nails in fastening thestrips in the frame, and, second, to provide in the base of said frame asmall aperture or sweat-hole to conduct oi the moisture or water ofcondensation that frequently forms on the inner surface of a glass,espeoially in windows and show-cases, owing to the differences oftemperature to which the two surfaces of the glass may be exposed. Iaccomplish these objects by the device illustrated in the accompanyingdrawings, which illustrate my invention as applied to a win dow, and inwhich- Figure l is a side elevation, partly in section, of awindow-sash, showing my improvements from the inside. Fig. 2 is across-section of the same on the line was of Fig. 1, showing theadjustments of the strips in the groove. Fig. 3 is a cross-section on.the line y y of Fig. 1, illustrating the position and form of thesweat-hole; Figs. 4 and 5, details of the fastening-strips.

A is a sash-frame containing two panes I) b of glass. The frame israbbeted about the four interior sides to form grooves 0, designed as abed for the glass and the fastening-strip. These grooves are ofsufficient depth and width to insure a good bearing for the glass aboutits exterior edge and a good bed or seat for the strips d. Thefastening-strips d d are shown separately in Figs. 4 and 5, in positionin Fig. 1, and in cross-section in Fig. 2. The top fasteningstrips d aremade with a convex outer surface and at each end are undercut to form atongue d which passes into an undercut d formedin the ends of the sidestrips d. A lap-joint is thus formed and the cut-out in the strip (1 iscurved so as to form a close joint with the convex surface of the sidestrip.

d is the key or locking-strip that fits in the bottom of the sash, asshown in Fig. 5, having a concave cutout of its ends adapted to fit andengage with the rounded or convex outer surfaces (1 cl and crowd themsecurely into the grooves c, forming the bed.

In Fig. 1 the right-hand side of the. sash is shown broken away to showthe entire fastening in place. The other side of the same figure showsthe complete sash with pane secured therein by the fastenings as itappears from the inside.

Fig. 2 illustrates in cross-section the sash, pane, and fastenings allin position.

The fastening-strips constituting the lock may be made of any desiredmaterial and of any exterior shape.

In Fig. 3 is shown in cross-section on the line y y of Fig. 1 the base,fastener, and base of the sash, showin the shape and position of thesweat-hole I have designed this latter feature in combination with myfastener to furnish a convenient escape for the water of condensationthat frequently forms on the inner surface of the pane and that worksits way down through the joint between the pane and the fastener, andbut for this means of escape would tend to swell and rot the parts. Bysuch an outlet the water, instead of collecting in the groove 0, cancscape to the outer surface of the sash and thus obviate suchdifliculty.

In operation, when it is desired to seta pane, the glass is laidsquarely in place on the rear face of groove 0. The top piece d is firstinserted and pushed hard into its seat in the groove 0. The side piecescl cl follow, and finally the key or locking-piece d is pushed intoplace and automatically secures and maintains the side pieces 61 dinplace. To remove a glass the operation is simply reversed, the key orlocking-piece being first removed by a penknife or other suitable means,and then the rest may be easily removed.

I am aware that wooden strips in various forms have been used aswindow-pane fasteners. I do not therefore claim such,broadly;

but

What I do claim, and desire to secure by Letters Patent, is-

1. A glass-fastener comprising a frame provided with the groove 0, incombination with the corresponding side strips d d, undercut at theirupper ends, the top strip d, having its ends undercut to fit themortised ends of d d, and the key or locking-strip 01 having its endscut concave to engage with the convex faces of d d, substantially asdescribed.

2. In a glass-fastener, the frame provided with the groove 0, incombination with the corresponding side strips d d, undercut at theirupper ends, the top strip d having its ends undercut to fit the undercutends d d, the key or locking-strip d of similar form, having its endscut concave to engage with the convex faces of cl d, and the sweat-holeh, formed in the base of the frame to conduct off any water that maypercolate down between the glass and the fastener, substantially as andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID CROSSER.
